Hello MAXIMIANO9F and welcome tot eh community! Unfortunately once you have used up the 30 day trial of a software it needs to activate the full version of the software by purchasing a license. In order to use a student version, you will need to reinstall windows and then install the software again on your machine. The trail versions are hard-coded into the software so that it is hard to remove except by reformatting the hard drive. This is your best bet to use the student version of the software unless you plan on getting a new machine. I hope this helps answer your question.
